This paper examines a growth model with endogenous consumption, labor-
leisure, and fertility. A fertility choice variable capturing both the
quality and quantity of the family size enters the utility function p
ositively, but it also generates time costs, Theoretical comparative d
ynamic results are derived for changes in exogenous production and uti
lity parameters. Employing post-World War II United States data. we es
timated the model using a structural VAR with imposed long-run restric
tions based on the theoretical predictions. The empirical results lend
support to the endogeneity of fertility choice and present dynamic re
sponses of each endogenous variable to employment, fertility, and outp
ut shocks.
